Motorcycles Under Kentucky Lemon Law

Motorcycles are excluded from Kentucky’s Lemon Law. The “motor vehicle” definition in § 367.840 expressly excludes motorcycles and mopeds (along with motor homes, conversion vans, farm machinery, and vehicles with more than two axles). So the 12-month / 12K Rights Period, the 4-attempts-or-30-day-OOS presumption, and the § 367.842 written-notice mechanism do not apply to a defective motorcycle. Kentucky riders instead rely on Magnuson-Moss, the UCC implied warranty of merchantability, and the Kentucky Consumer Protection Act (KCPA).

Why motorcycles fall outside the KY Lemon Law

The statutory exclusion is by vehicle type, not weight (Kentucky has no GVWR cap). Because motorcycles are named in the exclusion list, motorcycle buyers cannot invoke the § 367.842 lemon-law presumption — but they retain real remedies:

Magnuson-Moss Warranty Act — for breach of the manufacturer’s written warranty (federal-court access where the amount in controversy supports it).
UCC implied warranty of merchantability (Ky. Rev. Stat. § 355.2-314).
KCPA — for dealer or manufacturer misrepresentation or deceptive conduct, with punitive-damages potential.

Documentation for motorcycle cases

Repair orders for each attempt.
Mileage tracking — motorcycles often have lower annual mileage.
Photos / video of defects.
Service records — manufacturer-required maintenance.
OBD / module diagnostic codes (modern motorcycles).
Recall and TSB search.

Manufacturer defenses to motorcycle claims

“Aftermarket modifications” — exhaust, tuner, intake (common motorcycle aftermarket).
“Owner abuse / racing” — alleging track use, stunting.
“Improper maintenance” — alleging skipped valve adjustments.

Motorcycle-specific procedural considerations

No Lemon Law presumption — build the case on Magnuson-Moss breach-of-warranty and KCPA deceptive-conduct theories, documenting repair attempts as warranty-breach evidence.
Lower-dollar cases — many motorcycles cost $10K-30K, affecting the federal Magnuson-Moss $50K AIC threshold; state-court KCPA + UCC claims may be the better venue.
Distinctive sympathy facts — safety-critical defects create strong jury appeal.
BBB Auto Line coverage — varies by manufacturer.

Bottom line

Motorcycles and mopeds are excluded from the KY Lemon Law under § 367.840 — there is no lemon-law presumption for a defective bike. But Magnuson-Moss, the UCC implied warranty of merchantability, and the KCPA give Kentucky riders a real path to a refund, replacement, or damages. Get a free case review.
